This little sketch may not look like much, but the mobile pictured is about to be recreated into a 30-foot tall mobile. The average man is 5 feet, 10 inches tall. The average giraffe is 14 feet tall. And this mobile will be 30 feet tall. Take some time to wrap your mind around that while we get started on it. (But first, we may need some time to wrap our minds around it, too.)
